TYRUS MCOARGAR, OF MASONVILLE, IOWA, ASSIGNOR TO HIMSELF AND .SIMEON P.PETERS, 0F SAME PLACE.

Letters Patent No. 105,104, dated July 5, 1870.

The Schedule referred to in these Letter Patent and making part of thesame To all whom it may concern:

' Be it known that I, TYRUS MCOARGAR, of Masonville, Delaware county, inthe State of Iowa, have invented a new and Improved Spring-catch Bolt;and I hereby declare the following to be, a full and exact descriptionthereof, reference .being had to the accompanying drawing forming partof this specification.

The nature or essence of my invention consists in providing a bolt forconnecting separate pieces by passing through them, or for otherpurposes, with a spring-catch welded to the head of the bolt, so as to,be in one piece with it, and extending along in the same direction withthe bolt, so as to catch over some one of the pieces which the boltpasses through.

In the drawing hereinbefore mentioned- Figure 1 is a top view of acarriage-thill iron and a clip, connected by my improved bolt;

Figure 2 is a side view of the same; and

Figure 3, a view of the bolt.

The bolt A has the spring B welded to its head and extended alongparallel or nearly parallel with the bolt toward the opposite end of thesame, said spring being provided with a catch, 0, beveled on its frontor outer side, but forminga shoulder by its inner side at right anglesto the direction of the bolt or spring.

When the bolt is put through the pieces which it is to connect, thebeveled side of the catch meeting 1 said piecesvis forced back or liftedsomewhat until the bolt is through or in place, and then the catch willspring down over the edge of the piece passed through, and thus securethe bolt in its place.

To disconnect the parts again, it is only necessary to raise or drawback the spring-catch with the finger, when the bolt can be readilydrawn out.

This device is recommended by its extreme simplicity, its cheapness' anddurability, and its freedom from liability to be clogged with mud orice, so as to i make itinconvenient to remove it when required.

What I claim, and desire to secure by Letters Pat'- ent, is- Thecombination, with the bolt A, of the spring 13,

provided with a catch, 0, when weldedto the headof the bolt so as to bein one piece therewith, and extended along toward the opposite end ofthe same, substantially as and for the purpose herein set forth.

, TYRUS MCOARGAR.
